After years of using Slackware, I installed Crunchbang on a netbook about 4 or 5 years ago. The decision was made because Crunchbang worked with the hardware, but I really enjoyed using it, and the community was/is great. Then the developer killed the XFCE version, which was far more usable than the OpenBox variant.
At that point, I decided never to go with a one-man show again, and installed a minimal version of Debian. Given the size of the Debian development team, you don't have to worry about a single developer calling it quits and ending the project. In addition, as the Crunchbang dev noted, there's nothing in Crunchbang that you can't get from Debian.
